DefaultSingleSelectionModel

java.lang.Object
- javax.swing.DefaultSingleSelectionModel

All Implemented Interfaces:

Serializable, SingleSelectionModel
```
public class DefaultSingleSelectionModel
extends Object
implements SingleSelectionModel, Serializable
```
A generic implementation of SingleSelectionModel.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

```
public int getSelectedIndex()
```
    Description copied from interface: SingleSelectionModel
    
    Returns the model's selection.
    
    Specified by:
    
    getSelectedIndex in interface SingleSelectionModel
    
    Returns:
    
    the model's selection, or -1 if there is no selection

    SingleSelectionModel.setSelectedIndex(int)
  - setSelectedIndex
```
public void setSelectedIndex(int index)
```
    Description copied from interface: SingleSelectionModel
    
    Sets the model's selected index to index. Notifies any listeners if the model changes
    
    Specified by:
    
    setSelectedIndex in interface SingleSelectionModel
    
    Parameters:
    
    index - an int specifying the model selection

    SingleSelectionModel.getSelectedIndex(), SingleSelectionModel.addChangeListener(javax.swing.event.ChangeListener)
  - clearSelection
```
public void clearSelection()
```
    Description copied from interface: SingleSelectionModel
    
    Clears the selection (to -1).
  - isSelected
```
public boolean isSelected()
```
    Description copied from interface: SingleSelectionModel
    
    Returns true if the selection model currently has a selected value.
    
    Specified by:
    
    isSelected in interface SingleSelectionModel
    
    Returns:
    
    true if a value is currently selected
  - addChangeListener
```
public void addChangeListener(ChangeListener l)
```
    Adds a ChangeListener to the button.
    
    Specified by:
    
    addChangeListener in interface SingleSelectionModel
    
    Parameters:
    
    l - the ChangeListener to add
  - removeChangeListener
```
public void removeChangeListener(ChangeListener l)
```
    Removes a ChangeListener from the button.
    
    Specified by:
    
    removeChangeListener in interface SingleSelectionModel
    
    Parameters:
    
    l - the ChangeListener to remove
  - getChangeListeners
```
public ChangeListener[] getChangeListeners()
```
    Returns an array of all the change listeners registered on this DefaultSingleSelectionModel.
    
    Returns:
    
    all of this model's ChangeListeners or an empty array if no change listeners are currently registered
    
    Since:
    
    1.4
    
    See Also:
    
    addChangeListener(javax.swing.event.ChangeListener), removeChangeListener(javax.swing.event.ChangeListener)
  - fireStateChanged
```
protected void fireStateChanged()
```
    Notifies all listeners that have registered interest for notification on this event type. The event instance is created lazily.
    
    See Also:
    
    EventListenerList
  - getListeners
```
public <T extends EventListener> T[] getListeners(Class<T> listenerType)
```
    Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.
    You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultSingleSelectionModel instance m for its change listeners with the following code:
```
ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class));
```
    If no such listeners exist, this method returns an empty array.
    Parameters:
    
    listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
    
    Returns:
    
    an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
    
    Throws:
    
    ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener
    
    Since:
    
    1.3
